Question

我正在使用我的第一个Django项目，现在我有一些我根本不懂的错误！昨天我创建了两个表单：其中一个表单正在工作，第二个表单中的数据没有保存到数据库中。我试图解决这个问题，但现在他们都没有工作，我甚至与我的一个旧模板有同样的问题。你能告诉我我的错误是什么以及如何解决它们吗？

这是我的views.py：

的一部分

def listing(request):
    users_list = Person.objects.all()
    paginator = Paginator(users_list, 14) 
    page = request.GET.get('page')
    try:
        users = paginator.page(page)
    except PageNotAnInteger:
        users = paginator.page(1)
    except EmptyPage:
        users = paginator.page(paginator.num_pages)
    return render(request, 'friends_plans/list.html', {"users": users})

def add_wish_list(request):
    if request.method == 'POST':
        form = Wish_listForm(request.POST)
        if form.is_valid():
            newform = form.save(commit=False)
            newform.person = request.user
            newform.save()
        else:
            print form.errors
    else:
        form = Wish_listForm()
    return render(request, 'friends_plans/add_wish_list.html', {'form': form})

def add_comment(request, wish_list_id):
    person = request.user
    wish_list = get_object_or_404(Wish_list, pk=wish_list_id)
    if request.method == 'POST':
        form = Comment_to_wish_listForm(request.POST)
        if form.is_valid():
            newform=form.save(commit=False)
            newform.person = request.user
            newform.comment_to = wish_list
            wish_list.person = person
            newform.save()
        else:
            print form.errors
    else:
        form = Comment_to_wish_listForm()
    context_dict = {'form': form, 'wish_list': wish_list}
    return render(request, 'friends_plans/add_comment.html', {'context_dict':  context_dict})

这是我的urls.py：

app_name = 'friends_plans'
urlpatterns = [
url(r'^$', views.index, name='index'), # start page
url(r'^users/$', views.listing, name='listing'),
url(r'^(?P<person_id>[0-9]+)/wish_list/$', views.wish_list,    name='wish_list'),
url(r'^(?P<person_id>[0-9]+)/$', views.user, name='user'),
url(r'^(?P<person_id>[0-9]+)/(?P<day_id>[0-9]+)/$', views.day, name='day'),
url(r'^add_wish_list/$', views.add_wish_list, name='add_wish_list'),
url(r'^(?P<wish_list_id>[0-9]+)/comment/$', views.comment, name='comment'),
url(r'^(?P<wish_list_id>[0-9]+)/comment/add/$', views.add_comment,   name='add_comment'),
]

这是list.html：

{% extends 'friends_plans/base.html' %}
{% load staticfiles %}
    {% block title %} Users {% endblock %}
    {% block content %}
        <div id ="left">
            <div id="toptitle"> Friends' Plans members:</div>
            <table class="table">
                    <thead>
                      <tr>
                        <th>Photo</th>
                        <th>Name</th>
                        <th>Occupation</th>
                        <th>Days</th>
                        <th>Places</th>
                      </tr>
                    </thead>
                    <tbody>
                    {% for person in users %}
                      <tr>
                        <td><span> <img class="small_cat" src={% static  'images/cat3.jpg' %} /> </span></td>
                        <td><a href="{% url 'friends_plans:user' user.pk  %}">{{ person.username|upper }}</a></span></td>
                        <td><span>Student at {{   person.place_of_work_or_study}}</span></td>
                        <td>{{person.day_set.all.count}}</td>
                        <td>{{person.wish_list_set.all.count}}</td>
                      </tr>
                    {% endfor %}
                    </tbody>
                  </table>
            <div class="pagination">
                <div id="listing">
                    <span class="step-links">
                        {% if users.has_previous %}
                            <a href="?page={{ users.previous_page_number  }}">previous</a>
                        {% endif %}

                        <span class="current">
                            Page {{ users.number }} of {{  users.paginator.num_pages }}.
                        </span>

                        {% if users.has_next %}
                            <a href="?page={{ users.next_page_number  }}">next</a>
                        {% endif %}
                    </span>
                </div>
            </div>
        </div>
    {% endblock %}

这是add_wish_list.html：

{% extends 'friends_plans/base.html' %}
{% load staticfiles %}
{% block content %}
<h1>Add a wish_list</h1>
<form method="post"  action="/friends_plans:add_wish_list/">
    {% csrf_token %}
    {{form.as_p}}
    <input type="submit" value="Add wish_list" />
</form>
{% endblock %}

这是add_comment.html：

{% extends 'friends_plans/base.html' %}
{% block content %}

<h1>Add a wish_list</h1>
<form method="post"  action="">
    {% csrf_token %}
    {{form.as_p}}
    <input type="submit" value="Add comment" />
</form>
{% endblock %}

我理解这个问题与网址有关，但我不明白它是什么，以及为什么一切都很好用list.html之前我没有改变它！

Answer 1

在list.html中，您有def _query_data(self, sql_query: str, retries: int = 5): cursor = self._return_cursor(self.canvas_conn) for attempt in range(retries): try: cursor.execute(sql_query) except (ppg2.ProgrammingError, ppg2.OperationalError) as e: if 'Operation timed out' in str(e): print('Retrying, attempt {}'.format(attempt)) sleep(3) continue elif self.historical_connect: msg = 'Connected on last run, no longer available.' self.set_for_alert(msg) self.historical_connect = False raise ppg2.Error from e else: return self._iterate_results(cursor)，但您的变量名为{% url 'friends_plans:user' user.pk %}，而不是person。
